Therefore, it may be hindered in conditioning. Therefore, it is generally considered that the operating mechanism of the gas burners 1A, 1〇〇b may be formed on the inside of the glass top plate 10 2 with a detecting portion such as a capacitive sensing. Moreover, the surface of the glass top plate 1〇2 has a touch switch of the operation portion, and the upper surface of the glass top plate 102 is formed into a flat surface. However, when the touch switch is provided in this way, it may be covered by the ejected material from the conditioning material placed on the fire frame 104a, l4b, or the like, or the falling object on the glass top plate 1〇2. Touch the switch and make the touch switch open. Further, in this way, for example, when only the right burner 1b is used for heating conditioning, ίο may occur due to cooking/benefit from a pot or the like placed in the flame holder 1〇4b of the right burner i00b. Let the left burning $1Q()a ignition switch open and the left burner (10) & ignition problem. [The purpose of this book is to solve the above problems, and to provide a tool for preventing the point of view of the touch switch when the touch switch is switched from the non-detection state to the inspection state due to factors other than the user's operation. . Means for solving the problem, the present invention is achieved by the above object, and relates to an improvement of a stove comprising: a touch switch attached to a body of the stove covering the heating mechanism The top plate is disposed so that the user can instruct the start/stop of the heating mechanism to be started and stopped, and the contact or the approaching object is detected on the top plate; and the heating control mechanism is to grasp that the touch switch is in the detecting state or in the non-position The state is detected, and the actuator of the heating mechanism is controlled according to the result of the mastering. Further, the heating control means is configured to start the operation of the heating mechanism when the heating device 1275749 5 is in a stopped state when the touch switch is switched from the non-detection state to the detection state and then returned to the non-detection state. And when the heating mechanism is located at the operation «, when the touch switch is switched from the non-detection state to the detection state, the heating mechanism is stopped. (4) According to the present invention, the aforementioned heating (four) mechanism threatens the aforementioned touch mail 10 15 :==cut Until the detection state and then return to the non-detection state _ = the action of the heating mechanism, so even if the conditioning material or the material T rag, etc.) fall to the top plate and cover the touch switch and touch the detection state '(4) touch The touch switch does not return to the non-detection state, because ^ does not start the heating mechanism by the heating control mechanism. Further, when the heating mechanism is in the operating state, the twisting and protecting the touch switch is switched from the non-detecting state to the detecting state; and the tilting Z heating mechanism is actuated, so the user is in the heating mechanism==::Γ Refers to the front of the touch - touch the touch switch with your finger = =: In the stop operation of the mechanism, as long as the use situation is good. The heating mechanism can be stopped immediately, so that there are a plurality of the aforementioned touches, and the above-mentioned touch is: when the heating mechanism is in the stop state, at least two touch switches in advance are preset in advance. When the switch is switched to the inspection state and then returned to the non-detection state, the operation of the heating mechanism is started. According to the invention, the heating control mechanism starts the heating mechanism when the preset setting is 12 1275749 * the order of the plurality of touch switches is set from the non-detection state to the inspection, and the J-shaped core returns to the non-detection state. Acting. Moreover, it is extremely unlikely that the rice will switch from the double-measurement t to the non-detection state and then return to the detection state due to the overflow or the falling object. Therefore, by the present invention, Further, the heating mechanism is activated by the erroneous detection of the touch switch formed by the overflow or the falling object. The 8% is characterized in that the heating control mechanism stops when the heating device 10 15 is in the operating state, and when any one of the preset at least two touch switches is switched from the non-detecting state to the detecting state. Adding to action. According to the present invention, when the heating mechanism is in the actuating state, in the start instruction of the operation of the rain heating mechanism, all the touch switches of the pre-mosquito are switched from the detection state to the non-detection state. Since the control mechanism is in control, the above-mentioned pre-admission and contribution arrangement is not impossible to switch from the non-detection state. In the case of a fault of the like, the state of the above-mentioned pre-selected touch switch is switched to the detection state, and the former is stopped from non-reducing the failure of the touch switch, and the operation cannot be stopped. The possibility. Further, the heating mechanism is further characterized in that: the lighting mechanism is arranged to notify the user that the heating mechanism is a top lamp control mechanism, and is in the heating mechanism position and operation. , and 焭...

Further, each of the display portions of the operation unit 6 is composed of an LED provided on the inner side of the glass top plate 2 and a printed surface printed on the surface of the glass top plate 2 facing the LED. Further, when the LED is turned on, the display portion will be illuminated, and when the LED is turned off, the display portion will be turned off. In addition, the fire level _ display portion 15 & uses a bar composed of five lighting portions shown to display the number of lightings from the left side of the lighting portion to display the left burner such as the fire level (level i To the standard 5), for example, when the fire level of the left burning pure 11 1275749 is i, only the light portion of the left end of the bar display is illuminated, and the fire level of the left burner 4a is 5, the bar is displayed. The 5 lighting parts are all $ lights. Similarly, the fire level display unit 15b displays the fire level of the right burner 4b by displaying the number of lightings from the left side of the light bar shown by the five lighting units shown in the figure. Level 1 to level 5). Next, referring to Fig. 3, the controller 30 for controlling the operation of the entire stove is provided in the main body of the oven, and the switches of the operation unit 6 (the operation switch 10, the ignition preparation switch 11a, lib, and the firepower lowering switch 12a) The detection signal system 10 of the operating state (on/off) of the i2b and the firepower rising switches 13a, 13b) is input to the controller 30. Further, based on the control signal outputted from the controller 30, the gas main valve 40 for switching the supply and the blocking of the fuel gas to the furnace body 1 is controlled, and the fuel gas supply and the blocking for the left burner 4a are switched. The left burner switch 41a, the left-handed 15th fire control valve 42a for changing the supply flow rate of the fuel gas to the left burner 4a, and the high-voltage applied to the ignition electrode (not shown) of the left burner 4a. The left burner igniter 43a for generating a spark discharge, the right burner switch 41b for switching the fuel gas supply and the blocking for the right burner 4b, and the supply flow rate for changing the fuel gas to the right burner 4b.

Further, each display unit (the ignition preparation display units 14a and 14b, the fire level display units 15a and 15b, the unlock display unit 16 and the lock display unit 17) of the operation unit 6 is controlled in accordance with a control signal from the controller 30. ) Lights up/off and the buzzer 18 is turned on/off. 12 1275749 Further, the controller 30 includes: a heating control mechanism 31 for controlling the operators of the left burner 4a and the right burner 4b; and a lighting control mechanism 32 for performing the 卩 卩 6 The control of the lighting/xenon of each display unit and the informer using the buzzer 18. Here, as described above, the touch-on relationship provided in the operation unit 6 detects the presence or absence of an electrostatic body existing on the glass top plate 2, and therefore, the user touches the touch switch with a finger, as in the first (b) As shown in the figure, when only the left burner 4a is used to heat the conditioning material in the pot 20, the effluent 21 generating the conditioning material occurs and the escaping overflow 21 reaches the operation portion 6 and the right burner 4b is used. When the touch 10 switch constitutes an open state, or the falling object (rag, food, etc.) on the glass top plate 2 or the conditioning container placed on the glass top plate 2, the operation portion 6 is covered and the touch switch is formed. The state of the open state. Therefore, when the heating control mechanism 31 of the controller 30 switches the touch switch from the off state to the on state 15 due to factors other than the user's operation, the left burner 4a is configured to be misinterpreted. Or the treatment of the ignition treatment of the right burner 4b. Hereinafter, the processes will be explained in accordance with the flowcharts of Figs. 4 to 9. Further, the flowcharts of Figs. 4 to 9 are for the left burner 4a, however, the processing for the right burner 4b is also the same. First, steps 1 to 6 of FIG. 4 are used to recognize the process of switching the operation switch 10 20 from the off state to the on state and then to the off state. When the power is turned on and the controller 30 starts to operate, the "standby state" is established, and the heating control unit 31 waits for the operation switch 10 to be in the open state in step 1 of Fig. 4. Moreover, when the operation switch 10 constitutes an open state, then proceed to steps 2, 13 1275749 and start the 2-second timer and the 4-second timer, and in the loop formed by the following steps 3 and 〇 In step 30, it is confirmed that the operation switch 10 is maintained in the on state, and in step 3, the time of waiting for the second timer is reached. When the 2 second timer expires in step 3, that is, when the opening L of the operation switch 1 is continued for 2 seconds or longer, the routine proceeds to step *. Step 4 and step 5 are processed by the cover lamp control mechanism 32, and the lighting control mechanism 32 causes the unlocking display portion 16 to light, and simultaneously causes the buzzer 18 to sound, thereby informing the user that the operation switch 10 has been accepted. Operation. On the other hand, in step 3, the operation switch 1 is configured to be in the non-open state for 10 days, and it can be determined that the operation switch 1 is instantaneously configured to be in an open state due to noise or the like, and therefore, returning to step i, And the heating control mechanism 31 waits for the operation switch 10 to switch from the off state to the on state again. The heating control unit 31 is in the loop formed by the steps 6 and 35, and waits for the operation of the switch 1 in the step 6 of the step 15 to confirm the time of the 4-second timer. When the operation switch 10 is in the closed state in the step 6, that is, after the operation switch 10 is in the open state in the step, the switch 1 is returned to the closed state after the elapse of 4 seconds, then the process proceeds to step 7, and the heating is performed. The control mechanism 31 activates a 15-minute timer. On the other hand, when the 4-second timer expires in step 35, that is, when the open state of the operation switch 10 continues for 4 seconds or longer, the routine proceeds to step 80 of Fig. 7. Figure 7 is a process of child lock, and the lighting control mechanism 32 causes the unlock display portion 16 to be turned off in step 8A, and causes the lock display portion 17 to be illuminated in step 81, and the buzzer is enabled in step 82. 18 ringing. 14 1275749 Further, the heating control unit 31 waits for the operation switch 10 to be in an open state in the next step 83, and thus, until the child lock state is released by the operation of the operation switch 1〇, it is impossible to operate all the switches. Child lock status. If the user touches the operation switch 10 in the child lock state and operates the 5 switch! When the 〇 is turned on, the process proceeds from step 83 to step 84, and the heating control mechanism 31 starts the 4-second timer. Next, the heating control unit 31 is in the loop formed by the steps 85 and 90, and confirms whether the operation switch 1 is turned on in step 90, and waits for the time of the timer for 4 seconds in step 85. . When the timer seconds of the 4 seconds have elapsed in step 8510, that is, when the user continues to touch the operation switch 10 in the child lock state and the operation switch 10 continues to be in the on state for 4 seconds or more, the process proceeds to step 86. Further, in the next step 86, the lighting control means 32 turns off the lock display portion 17, and in step 87, the buzzer 18 is activated, and proceeds to step 1 of Fig. 4, whereby the child lock state Lifted. 15 When the operation switch 10 is in the closed state in the step 6 of FIG. 4, that is, after the operation switch 10 is in the open state in the step 1 and the switch 10 is turned off before the elapse of 4 seconds, the process proceeds to step 7. And the controller 30 will start a 15-minute timer. Next, step 14 to step 14 of Fig. 5 are used to recognize that the ignition preparation is turned on, and the switch is switched from the off state to the on state to the off state. The heating control mechanism 31 is in the loop formed by the steps 8 and 40. In the step 40, it is confirmed that there is no time in the timer, and in step 8, the ignition preparation switch 11a is switched from the off state to the on state. Resentful. Further, when the ignition preparation switch 11a is in the open state in step 8, then 15 1275749 proceeds to step 9 of Fig. 5. On the other hand, when the timer expires in step 40, that is, when the ignition preparation switch 11a is not in the open state 15 minutes after the operation of the switch 1 is turned off in step 6, the process proceeds to step 41. And the controller 3 turns off the unlock display unit 16 and causes the buzzer 18 to sound in step 42 and returns to step 1 to constitute a "standby state", whereby the user operates the operation switch 10 Thereafter, when the ignition operation of the left burner 4a is not performed 15 minutes before the elapse of the operation, the oven is returned to the "standby state". In step 9 of Fig. 5, the heating control unit 31 activates the one-second timer 10, and in the loop formed by the steps 10 and 50, confirms whether the ignition preparation switch 11a is in step 50. To turn on the state, wait for the time of 1 second timer in step 10. Further, when the timer time expires in step 10, that is, when the ignition preparation switch 11a continues to be in the on state for one second or longer, the process proceeds to step 11. On the other hand, when the one-second timer expires in step 50, that is, when the ignition preparation switch 11a is in the on state for less than one second, it can be determined that the ignition preparation switch 11a is instantaneously turned on due to noise or the like. Therefore, at this time, the process returns to step 7 of FIG. 4, and the heating control mechanism 31 waits for the ignition preparation switch 11a to switch from the off state to the on state again. Steps 11 to 12 are processed by the lighting control unit 32, and the lighting control unit 32 causes the ignition preparation display unit 14a to be turned on in step 11, and the buzzer 18 is turned on in step 12. Further, the heating control unit 31 activates the 2-second timer in step 13, and in the loop formed by the subsequent steps 14 and 55, it is confirmed in step 55 that the 2-second timer has expired 16 1275749 Waiting for the ignition preparation switch 11a in step 14 constitutes a closed state. When the ignition preparation switch 11a is in the closed state in step 14, that is, after the ignition preparation switch 11a is in the open state for one second, and the ignition preparation switch 11a has returned from the open state to the closed state within 2 seconds, the process proceeds to step 5. 15, and the heating control mechanism 31 starts a 10-second timer. On the other hand, when the two-second timer expires in step 55, that is, after the ignition preparation switch 11a is in the on state for one second, the ignition preparation switch 11a continues to be in the on state for two seconds, then proceeds to step 56. . Further, the controller 30 turns off the ignition preparation display portion 14a in step 56, and in step 57, causes the buzzer 18 to sound, and returns to step 7 in Fig. 4, whereby When the ignition preparation switch 1] is maintained in the open state, the processing after step 15 can be prohibited, and the ignition processing of the left burner 不会 is not performed. Next, step 19 to step 19 of Fig. 6 are used to identify the fire rise and open 15 off 13 & switch from the off state to the on state and then to the off state. The heating control mechanism 31 activates the 10-second timer in step 15, and proceeds to step 16 of FIG. 6 and confirms 10 seconds in step 60 in the learning path formed by steps 16 and 60. Whether or not the timer has reached the time, _ waits in step 16 for the firepower rise switch 13a to switch from the off state to the on 20 state. When the fire power rise switch 13a is in the open state in step 16, that is, after the ignition preparation switch 11a is in the closed state, the fire rise switch 13 & that is, the switch to the open state within 1 second, then proceeds to step 17. Steps 17 and 18 are processed by the lighting control mechanism 32, and the lighting control mechanism 32 is 17 1275749. In step 17, the fire level display portion 15a is turned on at level 4, and the beep is made in step 18. The device ι8 is audible and proceeds to step 19. Here, when the thermal power rise switch 13a is in the open state in step 16, the ignition processing of the left burner 4a which is carried out in the step 20 to be described later is performed, and the fire level display portion 15a is turned on in step 5, thereby , inform the user that the ignition instruction has been accepted. On the other hand, when the timer count time of 10 seconds has elapsed in step 60, that is, after the ignition preparation switch 11a is in the closed state, even if the firepower rise switch 13a has not been switched to the open state after the one-second power-cooling switch 13a has elapsed, the routine proceeds to step 61. The step is to use the process of the light-free control unit 32 in step 10, and the lighting control unit & performs the lighting preparation display unit 14a in step 61, and causes the buzzer 18 to sound in step 62. And returning to step 7 of Fig. 4, accordingly, the heating control mechanism 31 waits for the ignition preparation switch Ha to switch from the off state to the on state again. 15 20 The heating control mechanism 31 is constituted by the steps 19 and 65, and confirms the presence or absence of the timer for 10 seconds in the step 65, and waits for the firepower rise switch 13a to return to the closed state in step 19. . When the heating power rise switch 13a returns to the closed state in step 19, the process proceeds to a second step, and the heating control mechanism 31 is configured to activate the igniter 43a to cause the gas main valve 40 to be generated in a state in which the ignition is generated by the ignition. The left burner is opened by the on-off valve 41a, and the left burner fire regulating valve 42a is set to the firepower level 4, and the ignition process of the left burner 4a is performed. On the other hand, when the timer count time of 10 seconds is reached in step 65, that is, 1 'ignition preparation switch 11 a constitutes an open state and then fires within 10 seconds. ^ 18 1275749 13a switches from the off state to the on state and does not When returning to the closed state, the process proceeds to step 66. Steps 66 to 68 are processed by the lighting control unit 32 and the lamp control unit 32 causes the ignition preparation display unit 14a to turn on the light in step 66, and causes the fire level display portion 15a to 5 in step 67. And the buzzer 18 is sounded in the step anvil, and returns to step 7 of FIG. 4 . As described above, the heating control mechanism 31 is switched after the operation switch 10 is in the off state - the on state 4 is off state. When the ignition preparation switch 11a is switched in the off state 4 to the off state, the fire rise switch 10 13a is in the off state - the on state 1 is turned off, and the ignition process of the left burner 4a is performed. Therefore, even if the operation switch 10, the ignition preparation switch 11a, and the heating power rise switch 13a are switched from the closed state to the open state due to the overflow or the like, the left burner 4a is not ignited. Moreover, the three open relationships are performed only when the switches are switched in the predetermined state in the order of the switch 15 - the ignition ready switch fire rise switch 13a, in the closed state - the open state - the closed state, the ignition of the left burner 4a is performed. . Further, since it is difficult to construct a state in which the switches are switched in the closed state - the open state - the closed state in this order, it is possible to surely prevent the left burner 4a from being implemented by factors other than the user's operation. Ignition treatment. Next, the eighth and ninth drawings are flow charts of the flameout operation of the burner, and the eighth figure shows the flow chart when the operation switch 10 is in the open state in the combustion of the burner, and the figure 9 shows the ignition preparation in the combustion of the burner. The switch 11a forms a flow chart when 19 1275749 is turned on. First, referring to Fig. 8, in the combustion of the left burner 4a, if the operation switch 10 is in the ON state, the process proceeds from the step 1 to the step 1〇1, and the controller 30 starts the 1 second timer. Further, in the loop formed by the step 1〇2 and the step 11〇5, it is confirmed in step 110 whether or not the operation switch 1 is in the on state, and the time in the step 102 is waited for 1 second. When the one-second timer expires in step 102, that is, when the operation switch 1 continues to be in the on state for one second or longer, the process proceeds to step 1〇3. Steps 1〇3 to 105 and 107 are performed by the lighting control unit 32, and the lighting control unit 32 is in step 103 to step 1〇5 to cause the ignition preparation display unit 14a and the fire level display unit 15a. The unlocking display unit 16 is turned off. Further, in the next step 106, the heating control means 31 closes the left-burning switch valve 41a and the gas main valve 40, and causes the left burner 4a to ignite, and in step 107, the lighting control The mechanism 32 will cause the buzzer 18 to sound, and 15 informs the burner 4a of the flameout, and returns to step 1 of FIG. Next, referring to Fig. 9, in the combustion of the left burner 4a, if the ignition preparation switch 11a is in the on state, the process proceeds from step 12 to step 121, and the controller 30 starts the one second timer. Further, in the loop formed by the step 122 and the step 130, while the ignition preparation switch 20 na is in the open state in step 13A, the time for waiting for 1 second of the timer is reached in step 122. When the one-second timer expires in step 122, that is, when the ignition preparation switch 11a continues to be in the on state for one second or longer, the routine proceeds to step 123. Step 123 and steps 124 and 126 are processed by the lighting control unit 32, and 20 1275749 lighting control unit 32 turns off the ignition preparation display unit 14a and the fire level display unit i5a in steps 123 and 124. Further, in the next step 125, the heating control means 31 closes the left burner on-off valve 41a and ignites the left burner 4a, and in step 126, the lighting control means 32 causes the buzzer 18 sounds and informs the burner 4a of the flameout, and returns to step 7 of Fig. 4. Here, as described above, the ignition processing of the left burner 4a is performed when the operation switch 10, the ignition preparation switch 11a, and the heating power rise switch 13a are switched in the off state -> the on state -> the off state, so that When the user has performed the ignition operation of the left-row burner 4a, it is confirmed that none of the operation switch 1A, the ignition preparation switch 11a, and the fire-rising switch 13a is closed (the switch cannot be switched from the closed state to the closed state). In the state of the open state, the state is 0. Therefore, as shown in FIGS. 8 and 9, the left combustion is performed when the operation switch 10 and the ignition preparation switch 11a are switched from the off state to the on state due to the failure of the shutdown 15 during the ignition operation. The flameout processing of the device 4a can suppress the occurrence of the flameout of the left burner 4a due to the closing failure of the switch. Further, in the present embodiment, a gas burner having the gas burners 4a and 4b as the heating means of the present invention is shown. However, the present invention can also be applied to a stove having a heating mechanism of another type such as an electric heater. Further, the present embodiment shows a stove having a glass top plate 2 using heat resistant glass as the top plate of the present invention. However, the present invention can also be applied to a stove having a top plate of other materials such as stainless steel. Further, in the present embodiment, a static-capacity type touch switch is used as the stove of the touch switch of 21 1275749. However, the type of the touch switch is not limited thereto, and a light-emitting portion/light-receiving portion having infrared rays is used. The present invention can also be applied to a stove of a mechanical contact type touch switch such as a photoelectric switch or a touch switch.
